FLANGlNG-MACHINE FOR SWEAT-BANDS.

SPEGIFIGA'I'ION'forming part of Letters Patent No. 231,668, dated August 31, 1880.

Application filed J nly 1, 1880. (No model.)

To all whom at may concern Be it known that I, JOHN C. HERTLE, of the city of Brooklyn, county of Kings, and State of New York, have invented an Improvement in Hanging-Machines for Sweat -Bands, of which the following is a specification.

My invention relates to flanging-machines designed to flange sweat-bands for hat-bodies and it consists in mechanism operated in conjunction with the guide-foot and flan gin g-head whereby a uniform pressure may be brought to bear upon the guide and flanging-head to guide and flange sweatbands of various thicknesses with the same pressure automatically, and which mechanism is fully set forth in the following specification, shown in the accompanying drawings, and referred to in the appended claims.

The object of my invention is to so construct a fianging-machine for flanging sweat-bands that the pressure exerted by the flanging-head to flange the said band and the guide is the same for all sweat-bands, even though they vary greatly in thickness, and so produce uniform results.

In the drawings, Figure 1 is a perspective view of a Hanging-machine embodying in it my improvements. Fig. 2 is a section of a portion of same, showing the flanging-head and feeding-roller... Figs. 3 and 4 show sections of the slides which are situated on the pressure-bars, and the movement of which governs the pressure of the flanging-head and guide.

A is the frame of the machine. B is a shaft, having bearin gs in said frame A, and carrying on one end the feed-roller and former D, and on the other a pinion, E.

Situated over the shaft B is a frame; 0, which is pivoted at c and carries a shaft, O. This frame Gis kept from lateral movement and yet allowed movement on one end by moving in slots at a in frame A.

The shaft 0 has rigidly secured to it two collars,H and H, and upon one end the flanging-head G, and upon the other the pinion E, which meshes with pinion F on shaft 13 situated below. The shaft 0 is free to slide longitudinally in its bearings in frame 0.

Meshing with pinion E is a pinion, U,whicl1 the pulley L, is attached to a weight, L.

is secured upon one end of the driving-shaft U, carrying on the other end the drivingwheel U and workingin bearings at a a.

Passing through the frame A, at the top, and resting upon the frame 0, is a pin, 0 and resting upon this pin O is a lever, 0 having its fulcrum at A, and carrying a weight, 0 with which the pressure of the flanginghead Gupon the feedin g and former roll D is regulated and made uniform.

Attached to the frame A is a bar, I, and pivoted to this bar is the pressure-lever J, whose fulcrum is at j. This lever J carries an idler-roller, J, which rests against the collar H on shaft 0. Upon the outer end of this lever J is a slide, K, to which a cord, la, is attachedand then passes over the idler-pulley L, held upon shaft 1, and free to slide laterally thereon, said shaft being supported in a frame, T. The end of the cord it, after passing over y this means any pressure desired can be put upon the lever J, and, through the agency of the roller J, upon the shaft 0 and fl'angiughead G, to cause its flange g to press upon the flange d of the former-roller D. It is evident that this pressure must be uniform, however great the lateral movement given to the head G. If it is desired to lessen this pressure the slide-plate K is moved along the lever J toward its fulcrum j, the idler-pulley following it along its shaft l.

The slide K is provided with a knob, with which to move it, and on one side with aringpiece, If, to which the cord is attached, and on the bottom with a spring, it, kept in place by a bar, 15. The spring t presses tightly upon the lever J, and so holds the slideK wherever it is placed. Situated below this lever J is another and similar lever, Q, whose fulcrum is at q, and which has in place of the roller J a pin, q.

The slide R corresponds to slide K, and idlerpulley. S to pulley L. The pin q, attached to lever Q, presses against a collar, P, screwed 5 upon a shaft, 0, having hearings in the frame A, and in which it reciprocates longitudinally. Uponone end of this shaft 0 is the guide-foot V, which moves over a guideway, W, and

presses the sweat-band between the side of too the foot and the upright wall 20. Upon the other end of rod or shaft 0 is a nut or collar, P, carrying a pin, 19.

Situated under lever Q is another lever, N, whose fulcrum is at n, and which is attached or pivoted to the rod N at n. This rod N works through a hole in the frame A, and is pivoted at its outer end to a lever, M, whose fulcrum is at c, and which is provided with a pin, m, which rests against the pin 19 of the collar P on the shaft 0. The upper part of the lever M, near its fulcrum, rests against the collar H on the shaft (J, to which the flan gin ghead G is secured. Lever N is the operatinglever.

The operation is as follows: The lever N is pressed to the left, thereby forcing out the guide-foot V and raising the weight S by oscillating the lever Q, and forces out the flanging-head G to the position shown in dotted lines, raising the weight L by oscillating the lever J. These movements to the foot V and head G are caused by the movement of the rod N and leverM,which latter acts upon the shafts directly. The machine hein gin motion, the sweatband, after being sewed, is bent over and the edge placed between the foot V and the upright wall to and fed up to the flan ging-head G. The lever N is now relieved, and the weights S and L come into play, and, acting through the levers Q J, collars P H, and shafts O O, the head G and foot V are pressed back upon the sweat-band, which is now fed between the head G and former-roller D, and is flanged or has the edge creased and bent over. Should the sweat-band be very thick, and there should not be sufficient room vertically between the flanging-head G and roller D, then the former will be raised, lifting the weighted lever 0 By the adaptions of levers and weights to the flanging-head G and guide-foot V the same pressure is exerted automatically to flange all sweatbands, Whether thick or thin. The shafts B and O are rotated in opposite directions atabout the same speed; but the flanginghead G being very much greater in diameter than the former-roller, D, its periphery moves with a higher velocity; and since the sweatband is fed through the machine with a speed governed by the former-roller D, the said sweatband will be creased or flanged by the flanging-head pressing upon it and sliding over it at the same time. The collar P is adjustable on rod or shaft 0, so as to regulate the movement of the foot V against the wall or guide 10.

I claim- 1. In aflanging-machine for flanging sweatbands, mechanism which gives auniform pressure automatically, both laterally and vertically, to the flanging-head for any thickness of sweat-band, snbstantiallyin the manner set forth.

2. In a flanging-machine for flangingsweatbands, mechanism which puts the flanginghead automatically under a uniform pressure in a direction to the plane of said head, in combination with mechanism which puts the guide-foot under uniform pressure, automatically, in a direction parallel to that of the flanging-head, for the purpose of flanging varying thicknesses of sweat-bands with the same pressure, substantially as set forth.

3. In a machine for flanging sweat-hands, mechanism which operates the guide-foot in such a manner that a uniform pressure is put upon sweat-bands varying in thickness, automatically, thereby making the drag to the feed always uniform.

4. In aflanging-machine for flanging sweatbands, the combination of shaft 0, carried in a frame, 0, flanging-head G, former-roller D, pin G lever O weight *0, collar H, lever J, slide K, cord 70, idler-pulley L, shaft 1, and weight L, substantially as and for the purpose specified.

5. In a machine for flanging sweat-bands, the pressure-lever J, for imparting a lateral pressure to the flanging-head, in combination with an adjustable slide, K, cord 75. passing over idler-pulley L to slide upon shaft Z and adjust itself to the position of the slide, and weight L, substantially as and for the purposes described.

6. In a machine for flanging sweat-bands, mechanism which gives uniform pressure vertically and automatically to the flanging-head for sweat-bands of varying thicknesses, substantially in the manner set forth.
